Merge tag 'probes-fixes-v6.5-rc1' of git://git.kernel.org/pub/scm/linux/kernel/git/trace/linux-trace

Pull probes fixes from Masami Hiramatsu:

 - Fix fprobe's rethook release issues:

     - Release rethook after ftrace_ops is unregistered so that the
       rethook is not accessed after free.

     - Stop rethook before ftrace_ops is unregistered so that the
       rethook is NOT used after exiting unregister_fprobe()

 - Fix eprobe cleanup logic. If it attaches to multiple events and
   failes to enable one of them, rollback all enabled events correctly.

 - Fix fprobe to unlock ftrace recursion lock correctly when it missed
   by another running kprobe.

 - Cleanup kprobe to remove unnecessary NULL.

 - Cleanup kprobe to remove unnecessary 0 initializations.
